While the pictures make the PSU either look huge or the top down fan very small, it's surprisingly not the case. Well, it is longer than your standard ATX unit, but by only a few centimetres.

Style-wise it has an embossed Be Quiet! logo on both sides and the whole thing gets a shiny make-over that's super reflective but also picks up fingerprints very easily. It's a shame Be Quiet! didn't include a polishing cloth as well!

The single 12cm fan is built around one that features a fluid dynamic bearing (FDB) for silence. Typically ball bearings are claimed to offer a longer life and better reliability but for several years fluid bearings like this have been used in hard drive technology, and as products that are spinning at much higher RPMs that also need to be relied upon, we're pretty sure FDBs have shown their worth. The benefit of FDBs is that they are considerably quieter than ball bearings.

On the back Be Quiet! has again gone to considerable effort with the style of plugs it has used - making them very clearly labelled and even colour coordinated to reaffirm the difference between them. The sockets are well manufactured and we found no problem with the ease of their use - sometimes the plastic plugs just don't fit quite right, or they deform easily, but this is not the case here. Each plug socket is angled so that you can get your fingers in easily and they can be unclipped without a problem - that's nice attention to detail.

The only issue we found was one of personal preference - the colours make it look a bit kindergarten. We feel that in some ways it can be taken as condescending where instead this is a toy for a three year old to match the colours and plug numbers. Or, maybe it's just Be Quiet!'s way of getting PC builders to start young? “My first PC mod” anyone? No one certainly has this market yet and you’d only have to throw in a Gigabyte motherboard too and you're already half way there.

For this 650W, Be Quiet! uses a four rail design that fields a balanced 20A per rail, but the total power supply is just 52A between them. The 750W model (and upwards) features six rails but again are limited in the total amperage they can deliver, which progressively increases up to the 1,200W model.

Oh, and please excuse Joe's Multiwinia man, he's merely demonstrating the very reflective surface.
